Screen brightness change fn keys not working

[Copperis]

Hi,

The keyboard keys fn+f5 and fn+f6 do not work for changing the brightness under windows 10. Other fn keys, like for changing the volume - work.

Does anyone have a solution for this?

Hello Copperis,

Try updating BIOS, chipset and hotkeys support from HP website.

Ensure Windows is up to date.

Go to BIOS,

Choose Restore defaults

Hi Copperis,

Try updating the BIOS driver and hotkey support driver using the following link:

BIOS Driver:

HP Hotkey Support Driver:

Hi. I tried this solution but it's still not working for me. I updated the BIOS and I installed the latest Hotkeys driver.

As OmarZD wrote, that solution doesn't work for me either.

I dont know if it helps anyone, but I bought a second hand zbook studio, and out of the box the brightness screen fn was not working. I called HP support, and they pointed me to SoftPaq Download Manager. I downloaded it and I let it installed everything it detected missing (including a hot key driver and a later BIOS) and the fn key started working.

We also have this problem and havent gotten a solution from HP. But there is a workaround you can use to get it working.

Simply change the keyboard driver to "Standard PS/2 keyboard" and the FN-keys will magically start working 🙂

Thanks Andreas! Great magic.

Hello,

A better solution is to install .NET 3.5  as described here: 

https://docs.microsoft.com/en-us/dotnet/framework/install/dotnet-35-windows-10

then install the Windows 7 x64 hot keys driver for your model

reboot, enjoy 🙂
